Implementation of WG Stream Cipher with Involution Function
No full textAbstractThis paper present a new hardware design of WelchGong (WG)128 cipher. The proposed WG Stream cipher use an involution function block, for increasing the security of private data. The hardware complexity of involution block is very less. Together with the involution block the randomness property of the resulting WG cipher will increases
The Characterizations of WG Matrix and Its Generalized Cayley–Hamilton Theorem
No full textBased on the core-EP decomposition, we use the WG inverse, Drazin inverse, and other inverses to give some new characterizations of the WG matrix. Furthermore, we generalize the Cayley–Hamilton theorem for special matrices including the WG matrix. Finally, we give examples to verify these results

This species is widely distributed in South Korea and was collected on various species of Araliaceae and Apiaceae together with E. nubilus and E. rotundus during the present study. This species overwinters as adults. Remarks. This species is similar to E. brevis, E. humeralis, and E. interstinctus in general appearance but clearly distinguished by the genital segments of both sexes and the parameres of the male. In detail, males of E. yunnanus have a single median setal tuft on the ventral margin of the pygophore, and a heavily sclerotized and pigmented median process on the infolding (Fig. 35, 44, 47); males of the above three species have two pairs of submedian setal tufts on the ventral margin of the pygophore and lack such a process (Figs. 41–43). The posterior margin of the eighth abdominal segment of the female of this species is very deeply emarginate (Fig. 36), while that of the above three species is only weakly emarginate (E. humeralis, E. interstinctus: Figs. 32, 34, respectively) or slightly protrudes in the middle (E. brevis: Fig. 30). The paramere of this species is somewhat similar to that of E. humeralis because the distal margin is oblique (Figs. 50, 51), while that of E. brevis and E. interstinctus is nearly perpendicularly truncate distally (Figs. 48, 49); however, the lateral margin of the paramere is sinuate in E. yunnanus (Fig. 51), while it is simple in E. humeralis (Fig. 50). The scutellum is usually provided with a dark triangular or wedge-shaped median spot and its lateral margins are also darkly suffused at least basally (Figs. 11, 12, 57). Although E. humeralis also frequently has a dark triangular median spot at the base of the scutellum, this spot is always broad and apically rounded (Figs. 9, 10, 56), whilst elongate and apically tapering in E. yunnanus (Figs. 11, 12, 57). This species was described from Yunnan, Southwest China (Hsiao & Liu 1977), and subsequently recorded from Songbai Township, Hubei, Central China (Liu 1979). The identity of the species was confirmed by reexamination of the type material deposited at NKUM. The present record from Korea, representing the first record for the country, considerably extends the known distribution of the species. Elasmostethus kansuensis Hsiao & Liu, 1977, was recorded from Korea by Lee et al. (1994) without further remark. The type material of E. kansuensis (holotype, allotype, 2 male and 1 female paratypes from Tianshui, Gansu, China) are deposited in TMNH and were reexamined during the present study; it distinctly differs from all species treated in this paper. Morphologically it is rather similar to E. yunnanus, and the infolding of the ventral rim of its pygophore is also provided with a median process. However, it can easily be differentiated from the latter species by its less produced humeri; the posterior margin of the pygophore being posteriorly broadly produced in the midline to the level of posterolateral angles of segment VII and almost straight at the two sides in ventral view (narrowly produced in the midline, far surpassed by apices of posterolateral angles of segment VII in E. yunnanus), and the posterior margin of segment VIII of female being weakly arched at the two sides (broadly rounded in E. yunnanus). No Korean specimen of E. kansuensis could be examined during the present study because we could not find the specimens of E. kansuensis presented in Lee et al. (1994) in any institutions of Korea, and, in addition, there was no further record since the record of Lee et al. (1994). The record of Lee et al. (1994) probably pertains to E. yunnanus.Published as part of Jung, Sunghoon, 2017, Review of the genus Elasmostethus (Hemiptera: Heteroptera: Acanthosomatidae) from the Korean Peninsula, pp. 351-365 in Zootaxa 4320 (2) on pages 361-362, DOI: 10.11646/zootaxa.4320.2.9, http://zenodo.org/record/89194
